Abstract
A guiding catheter for use in coronary angioplasty and other cardiovascular interventions which incorporates a transition element in the shaft of the device. The transition element which has a different flexibility than the sections immediately proximal and distal to it, creates a zone in the catheter shaft which is either more or less flexible than the rest of the shaft. The transition element allows a portion of the shaft to be made more rigid or more flexible, without changing the flexibility of the other portions of the shaft. The transition element also allows for a differential flexibility to be added to the catheter shaft.
